mt76_dma_cleanup() already disables tx napi before deleting it, but
it still removes rx napi instances while they can remain enabled on the
normal device remove path. On mt7915 this triggers a warning.
Disable each rx napi instance before netif_napi_del() and page pool
destruction. This fixes repeated warnings on rmmod mt7915e on
mt7915e/mt7981b.
